Problems solved by technology

On the one hand, this is not conducive to the electromagnetic field entering the crucible. On the other hand, it has to use a large blank to make the crucible. The inner cavity of the crucible must be dug out from the whole blank, which is a great waste of material.
Processing a large number of crucible flaps and intensive welding on a large blank is difficult to process and prone to errors, and once an error occurs in a certain part, the whole will be scrapped

Embodiment 1

[0072] Embodiment 1, the crucible piece has a small horizontal hole, and is assembled by welding the horizontal tube:

[0073] The crucible has a circular cross-section, an internal channel pattern, and is divided into 18 petals. It is assembled through the horizontal hole by welding. The crucible wall and the crucible bottom are in an integrated structure. The inner wall of the crucible bottom (02) is conical and the bottom surface is flat.

[0074] The blanks of the crucible pieces are cut from a thick copper plate, a total of 18 pieces, including the shape of the crucible bottom (02). Drill a deep hole (12) upwards from the bottom surface of the crucible sheet, and the distance between the upper end of the deep hole and the upper end surface of the crucible sheet is about 20mm. according to Figure 5b , d and Figure 6c Proceed to process and assemble the crucible pieces in the indicated manner: for a set of 6 pieces, for two of them a cross hole (16) is machined at one e...

Embodiment 2

[0076] Embodiment 2, the crucible piece has a small horizontal hole, and is assembled through the horizontal hole by means of a mechanical seal:

[0077] The crucible has a circular cross-section, an internal channel pattern, the crucible wall is divided into 16 petals, the bottom of the crucible is a split structure, and is divided into 8 petals according to the radiation direction, there is no injection port, the upper surface is a conical surface, and the lower surface is a plane.

[0078] Crucible wall making:

[0079] 1) Making crucible pieces: copper rods with rectangular cross-sections are made according to Figure 4 Cut in the manner shown, the length of the crucible blank is equal to the height of the crucible wall, a total of 16 pieces. A step is welded on the inner wall of the lower end of each crucible piece for installing the crucible bottom. A deep hole is drilled upwards from the bottom surface of the crucible sheet, and the distance between the upper end of t...

Embodiment 3

[0093] Embodiment 3, using mechanical seals to assemble through horizontal holes:

[0094]The crucible has a circular cross-section, an inner channel pattern, and the crucible wall is divided into 16 petals. The bottom of the crucible is a split structure, which is divided into 8 petals according to the radiation direction, with a betting port and a cone shape.

[0095] These are substantially the same as the cold crucible of embodiment two, but there are also differences in structure: a. the bottom of the crucible (02) is directly contained in the lower end surface of the crucible wall (01), so the end of the crucible sheet (03) does not process steps, But this makes aqueduct (06) have to connect from the outer wall of crucible wall;

[0096] Crucible wall production process:

[0097] 1) Make the crucible piece: Except that the upper end of the crucible piece needs to be reserved for assembling the crucible (26) when cutting the blank, and the step is not made at the lower ...

Abstract

The invention relates to a structural designing and manufacturing method of a cold crucible for vacuum induction melting, in particular to a structural designing and manufacturing method of a cold crucible provided with a single-layer pipe cooling passage and spliced by simple elements. A crucible bottom and a crucible wall are of a split structure, the crucible wall is spliced by same crucible discs with simple structures, a cooling passage adopts a crawl single-layer pipe mode, and the whole cooling passage is seperated into a plurality of crawl units; each crawl unit comprises independent inlet and outlet and a plurality of passage sections, wherein a first passage section enters into a second passage section after passing through a crucible disc and bending 360 degrees and passes through next crucible disc in negative direction, and the rest can be done in the same manner, the trend of each section is along the length direction of the crucible discs; each crawl unit can comprise one, two, three or more passage sections, and the largest number of the passage sections can be equal to the number of the crucible discs. Because the cooling passages pass through every crucible disc, the crucible discs are provided with inner holes vertical to end faces.

Description

Technical field [0001] The invention relates to a structural design and manufacturing method of a cold crucible for vacuum induction smelting, in particular to a structural design and manufacturing method of a cold crucible assembled from simple components with a single-layer tube cooling channel. technical background [0002] Vacuum induction melting technology is an advanced melting technology, which eliminates the pollution of the furnace charge by the atmosphere and heating source during the melting process. However, this technique cannot exclude the reaction of the crucible material with the charge. In order to prepare products with particularly high purity requirements and smelt active materials, a more advanced cold crucible vacuum induction melting technology (hereinafter referred to as "induction cold crucible technology") appeared at the end of the last century-it replaced metal (mostly copper) crucibles The crucible is made of ceramic material, and a certain levi...
